Answer:
9.09%
Step-by-step explanation:
John Salary = $80,000.
Raise = 10% of salary = 10/100*80,000=$8000
New Raised Salary = 80000 + 8000 = $88000
Cut back = 80000
Decrease % = (88000-80000)/88000*100
Decrease % = 8000/88000*100
Decrease % = 9.09%
Answer: (i) 4x - 40 = 76
(ii) 29 questions
Step-by-step explanation:
Let the total number of questions be x.
Since he received 4 points for every correct answer and he got 10 answers wrong , this means he lost 40 points , the equation thus become
4x - 40 = 76
To find the value of x , add 40 to both sides
4x = 116
divide through by 4
x = 29
Therefore , there are 29 questions on his math test
Answer:
